Mathematical analysis of a randomized method for fractional Carathéodory type equation with time-irregular coefficients ZAMM (IF 2.3) Pub Date : 2024-02-13 Ye Hu, Fang Cheng, Beibei Hu, Shahzad Sarwar
In this work, we present a novel error analysis for fractional Carathéodory type differential equations with time irregular coefficients. It is based on the filtered probability space, with Banach spaces Lp(Ω;Rd)$L^p(\Omega;\mathbb {R}^d)$ and then discretized using the randomized numerical method, which is a prototype derived from the Monte Carlo method. We derive Lp(Ω;Rd)$L^p(\Omega;\mathbb {R}^d)$

Numerical and statistical analysis of unsteady hydromagnetic hybrid nanofluid flow in a porous medium over an inclined disk with dissipative heat transfer ZAMM (IF 2.3) Pub Date : 2024-02-15 Ajay Kumar Kar, Premful Kumar, Ramayan Singh, Raj Nandkeolyar
The present analysis deals with the three-dimensional radiative, convective hybrid nanofluid flow over a rotating and stretching inclined disk under the action of the applied magnetic field, Joule's heating, and viscous dissipation effects. The mathematical model considers nanoparticles graphene oxide (GO) and molybdenum disulfide (MoS2$_2$) suspended in water as the base fluid within a Darcy medium
